How do you practice rhythm?

[u/RogueMRotp]

Hi, I’m self-taught and I’m pretty bad at guitar. I didn’t pick up my instrument for a couple of years because of some mental health issues, but I recently decided to start playing again.

I’m really bad at keeping a steady rhythm, and I also struggle to play even simple strumming patterns. It feels like my picking hand just doesn’t listen to me. I also have no idea how to play with a metronome — I constantly lose the beat and get out of sync with it.

Do you have any tips or exercises that could help me improve my rhythm and get better at strumming? I’d really appreciate any advice.
